Ciara wants everyone to know she's standing by her man ... saying Russell Wilson is still a champion -- despite the fact the Hawks got rocked this weekend.

After Cam Newton and the Panthers steamrolled Seattle, Ciara went to Instagram and wrote a love letter to the Seahawks QB.

"My Love. I am So Proud Of You! What A Phenomenal Season It's Been. You Never Cease To Amaze Me With Your Faith, Will, Integrity, Resilience, and Courage."

"You Always Find A Way To Make Things Happen When It Seems Absolutely Impossible! Constantly Inspiring Me and Others Around. A Rare Breed You Are. My Champ. The Best Is Yet To Come. I Love You ❤️ #GoHawks #3."

The good news for Ciara ... looks like next weekend just opened up for a date night.
